     In order to solve the problem of recognizing the continental thin-interbedded sandbodies in Fuyu oil res- ervoirs of Songliao Basin, the seismic sedimentology is developed and improved, thus the techniques of continental seismic-sedimentology-sandbody identification and sedimentary microfacies interpretation are established. On the basis of fine calibration by well-seismic combination, the isochronism of the sequence correlation is ensured by means of the comparison of fluvial-facies individual layer correlation; and furthermore with the help of the fine in- terpretation of the seismic horizons leveled by the reference standard zones, the interpretation precision of the fourth-order sequence interfaces is enhanced; based on the extraction of the optimal time window seismic daughter, the optimization of the effective seismic attributes, the recovery of relative palaeogeomorphology, the analysis of the sedimentary evolution and moreover the seismic sedimentary microfacies explanation made by the integration of well and seismic data according to the seismic attributes, a true sense of the large-scale sedimentary microfacies industri- al mapping is realized.
